Description

The outer heat boiler of internal combustion

Technical field

This utility model relates to field of boilers, particularly relates to the outer heat boiler of a kind of internal combustion.

Background technology

Existing boiler, the structure of its hearth wall usually outermost layer be body of heater, intermediate layer be water tank, fill in this water tank Equipped with the water that need to heat, innermost layer is the flame retardant coating etc. made of refractory material, is burner hearth in the inner side of flame retardant coating, biomass or Coals etc. burn in this burner hearth, and the water in water tank absorbs the heat in burner hearth by flame retardant coating.Because the effect of heat insulation of flame retardant coating has Limit, the heat absorbed in burner hearth that the water in water tank can be more, although so not resulting in the waste of heat, but due to water Boiling temperature is only about 100° centigrade so that in burner hearth, the temperature at flame retardant coating is significantly less than biomass or coal etc. Ignition temperature, causes in burner hearth the biomass at flame retardant coating or coal etc. to be difficult to fully burn.It was verified that near fire-resistant Biomass within layer 5CM to 8CM or coal etc. are relatively low due to temperature, are difficult to fully burning, cause the waste of the energy.

Summary of the invention

The purpose of this utility model is to provide the outer heat boiler of a kind of internal combustion using flue gas and hydrothermal exchange to carry out adding hot water.

The purpose of this utility model is achieved in that the outer heat boiler of described internal combustion, including housing and the bottom of housing The burner hearth being provided with, it is characterised in that: in housing, it is provided with a plurality of fume pipe, the smoke inlet of each fume pipe and the smoke evacuation of burner hearth Mouthful communicating, the external smoke extractor of outlet flue of each fume pipe is got rid of, have between the inwall and fume pipe of housing water, water be from Water inlet that the bottom of housing is provided with introduces, and water can carry out heat exchange with fume pipe, with the inwall and fume pipe of heated shell it Between water, make hot water, be provided with hot water outlet and steam outlet on the top of housing, be respectively used to hot water and water outlet Steam.

Described each fume pipe be shaped as layout of circling round from bottom to top, in fume pipe turning point, cleaning door is set, Closed by insulated door outside cleaning door.

Advantage of the present utility model is: burner hearth igniting fired biomass, timber or coal etc. in this utility model, now in burner hearth The flue gas produced leads in fume pipe through the exhaust opening of burner hearth, fume pipe can with water carry out heat exchange with the inwall of heated shell with Water between fume pipe, makes hot water, and hot water can be drawn from hot water outlet, and steam can also draw from steam outlet Go out；Flue gas after heat exchange is got rid of from smoke extractors such as chimneys.Impurity in fume pipe or dirt can by open every Popular removing.This utility model has simple in construction, heat exchange area is big, efficiency is high, can save energy 30%, dirt easy to use, less The features such as dye.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is cross section structure schematic diagram of the present utility model.

Detailed description of the invention

With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings:

As shown in Figure 1 and Figure 2, the outer heat boiler of internal combustion described in the utility model, the bottom including housing 1 and housing is provided with Burner hearth 2, the outer wall of housing 1 is provided with thermal insulation layer, and housing 1 can be circular or oval, and its construction features is for set in housing 1 Having a plurality of fume pipe 4, the smoke inlet of each fume pipe 4 to communicate with the exhaust opening 3 of burner hearth 2, the outlet flue of every fume pipe 4 is external Chimney 5 smoke extractor such as grade, having water, water between the inwall and fume pipe 4 of housing 1 is the water inlet 6 being provided with from the bottom of housing 1 Introducing, water can carry out heat exchange with fume pipe 4 or flue gas therein, with the water between inwall and the fume pipe 4 of heated shell 1, Make hot water, be provided with hot water outlet 7 and steam outlet 8 on the top of housing 1, be respectively used to hot water and water outlet is steamed Gas, can be provided with Pressure gauge and water-level control apparatus on the top of housing 1, and Pressure gauge controls the water vapour pressure in housing 1, with Exempt from it phenomenons such as pressure excessive generation blast, water-level control apparatus for controlling the water level in housing 1, the water in housing 1 When position is not enough, water feed apparatus can be started such as: tap water and water intaking valve, be allowed to be incorporated in housing 1, when housing 1 from water inlet 6 Interior water level reaches setting when requiring, the water intaking valve that can close water feed apparatus makes tap water not enter.Flame (the highest temperature in burner hearth Degree) directly absorbed by the water in housing 1, therefore heat exchange area is big, efficiency is high, can save energy 30%.

Described each fume pipe 4 is shaped as layout of circling round from bottom to top, can arrange cleaning door in fume pipe turning point, Closed by insulated door 9 outside cleaning door.

During utility model works, open burner hearth 2 and water feed apparatus such as: tap water and water intaking valve, make tap water enter shell Internal, then burner hearth 2 is lighted a fire fired biomass, timber or coal etc., and the flue gas now produced in burner hearth 2 leads to through the exhaust opening 3 of burner hearth 2 In fume pipe 4, fume pipe 4 can and water carry out heat exchange with the water between inwall and the fume pipe 4 of heated shell 1, be allowed to into For hot water, hot water can be drawn from hot water outlet 7, and steam can also be drawn from steam outlet 8；Cigarette after heat exchange Gas can be drawn by water tank purification, air-introduced machine and be got rid of from smoke extractors such as chimneys 5.Impurity or dirt in fume pipe 4 can To remove by opening insulated door 9.

The not described part of this utility model is prior art.
